Do you know the [Waveform] operator? It helps to debug things related to colors-ranges and alpha-channel.

I spent some time looking into this issue and discovered, that the blend-mode of the [Layer2d]-Operators seems to implement an invalid blending for alpha. You can fix this issue be inserting any image-effect Operator like [ChannelMixer] or [ColorGrade] between [RenderToImage] and [RenderFiles]

You could als try to connect the [RenderToFiles] directly to the [BlendImagesAdd] below the Layer2d. I investigate some more though.
